Affordability: ★★★★★☆☆☆ The price of gas water heater is still affordable in water heater. Take a domestic brand product as an example, the price of 10L is 1 109 yuan, and the price of 13L is 1340 yuan. Products of imported brands are at least several hundred yuan more expensive.

● For a family of three, it is more appropriate to choose a gas water heater with the specification of 10- 13L.

● The water heater with constant temperature control is three or four hundred yuan more expensive than the general water heater, but it can avoid the cold caused by cold and hot water temperature, which is more cost-effective than spending 1,000 yuan on a constant temperature faucet.

● Gas water heaters are more suitable for families with small living areas. If the kitchen and bathroom at home are far away, you can consider installing an electric water heater in the bathroom and a gas water heater in the kitchen.

● If you need to use hot water at home at any time every day, and the heat preservation effect of the water heater is good, then you should always keep the water heater energized and set it in the heat preservation state, because the electricity used for heat preservation for one day is less than that used for heating a box of cold water to the same temperature. This not only facilitates the use of hot water, but also achieves the purpose of saving electricity.

When it comes to safety and energy saving, gas water heaters and electric water heaters are not the "rivals" of solar water heaters. Although it is expensive, you don't need to pay electricity and gas bills. As long as there is sunshine, you can use hot water at any time. Many merchants suggest that consumers add an electric heating rod to the solar water heater, which can be used as an electric water heater in the case of insufficient light.

Safety: ★★★★★☆ Not afraid of gas poisoning and electric leakage, it is safe to use solar water heaters. But the influence of lightning weather should also be considered. The solar water heater should be installed in a certain position below the lightning protection zone (needle) of the building or a lightning rod should be installed to avoid potential safety hazards.

● When taking a shower, if the water in the solar water heater happens to be used up, the user can put some cold water, and push the hot water out of the vacuum tube by using the principle that the cold water sinks and the hot water floats, and then take a shower. If there is still a little hot water in the solar water heater after bathing, the hot water can be washed by one person after a few minutes of cold water, and the hot water output of each vacuum tube is 6-8 liters.

According to the weather forecast, the water quantity can be determined and the satisfactory water temperature can be obtained. If it is sunny tomorrow, you can irrigate it; Cloudy or cloudy, half a box of water; If it rains, keep the original water instead of cold water.

● Don't think that choosing a small solar water heater is like 25? Color TV, compared with 29? Just smaller, as long as you can see. In fact, there are essential differences between big solar energy and small solar energy. The big one allows you to use hot water all the time. Everyone uses hot water and everything uses hot water, which is more cost-effective in the long run.
